<p>The <a class="link" href="gio-GSettingsSchema-GSettingsSchemaSource.html#GSettingsSchemaSource"><span class="type">GSettingsSchemaSource</span></a> and <a class="link" href="gio-GSettingsSchema-GSettingsSchemaSource.html#GSettingsSchema"><span class="type">GSettingsSchema</span></a> APIs provide a
mechanism for advanced control over the loading of schemas and a
mechanism for introspecting their content.</p>
<p>Plugin loading systems that wish to provide plugins a way to access
settings face the problem of how to make the schemas for these
settings visible to GSettings.  Typically, a plugin will want to ship
the schema along with itself and it won't be installed into the
standard system directories for schemas.</p>
<p><a class="link" href="gio-GSettingsSchema-GSettingsSchemaSource.html#GSettingsSchemaSource"><span class="type">GSettingsSchemaSource</span></a> provides a mechanism for dealing with this by
allowing the creation of a new 'schema source' from which schemas can
be acquired.  This schema source can then become part of the metadata
associated with the plugin and queried whenever the plugin requires
access to some settings.</p>
<p>Consider the following example:</p>

<p>The code above shows how hooks should be added to the code that
initialises (or enables) the plugin to create the schema source and
how an API can be added to the plugin system to provide a convenient
way for the plugin to access its settings, using the schemas that it
ships.</p>
<p>From the standpoint of the plugin, it would need to ensure that it
ships a gschemas.compiled file as part of itself, and then simply do
the following:</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
    <tbody>
      <tr>
        <td class="listing_lines" align="right"><pre>1

        <td class="listing_code"><pre class="programlisting"><span class="gtkdoc opt">{</span>
  GSettings <span class="gtkdoc opt">*</span>settings<span class="gtkdoc opt">;</span>
  gint some_value<span class="gtkdoc opt">;</span>

  settings <span class="gtkdoc opt">=</span> <span class="function">plugin_get_settings</span> <span class="gtkdoc opt">(</span>self<span class="gtkdoc opt">,</span> NULL<span class="gtkdoc opt">);</span>
  some_value <span class="gtkdoc opt">=</span> <span class="function"><a href="GSettings.html#g-settings-get-int">g_settings_get_int</a></span> <span class="gtkdoc opt">(</span>settings<span class="gtkdoc opt">,</span> <span class="string">&quot;some-value&quot;</span><span class="gtkdoc opt">);</span>
  <span class="gtkdoc opt">...</span>
<span class="gtkdoc opt">}</span></pre></td>
      </tr>
    </tbody>
  </table>
</div>

<p></p>
<p>It's also possible that the plugin system expects the schema source
files (ie: .gschema.xml files) instead of a gschemas.compiled file.
In that case, the plugin loading system must compile the schemas for
itself before attempting to create the settings source.</p>

<p>Attempts to create a new schema source corresponding to the contents
of the given directory.</p>
<p>This function is not required for normal uses of <a class="link" href="GSettings.html" title="GSettings"><span class="type">GSettings</span></a> but it
may be useful to authors of plugin management systems.</p>
<p>The directory should contain a file called <code class="literal">gschemas.compiled</code> as
produced by the glib-compile-schemas tool.</p>
<p>If <em class="parameter"><code>trusted</code></em>
 is <a href="../glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a> then <code class="literal">gschemas.compiled</code> is trusted not to be
corrupted. This assumption has a performance advantage, but can result
in crashes or inconsistent behaviour in the case of a corrupted file.
Generally, you should set <em class="parameter"><code>trusted</code></em>
 to <a href="../glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a> for files installed by the
system and to <a href="../glib-Standard-Macros.html#FALSE:CAPS"><code class="literal">FALSE</code></a> for files in the home directory.</p>
<p>If <em class="parameter"><code>parent</code></em>
 is non-<a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> then there are two effects.</p>
<p>First, if <a class="link" href="gio-GSettingsSchema-GSettingsSchemaSource.html#g-settings-schema-source-lookup" title="g_settings_schema_source_lookup ()"><code class="function">g_settings_schema_source_lookup()</code></a> is called with the
<em class="parameter"><code>recursive</code></em>
 flag set to <a href="../glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a> and the schema can not be found in the
source, the lookup will recurse to the parent.</p>
<p>Second, any references to other schemas specified within this
source (ie: <code class="literal">child</code> or <code class="literal">extends</code>) references may be resolved
from the <em class="parameter"><code>parent</code></em>
.</p>
<p>For this second reason, except in very unusual situations, the
<em class="parameter"><code>parent</code></em>
 should probably be given as the default schema source, as
returned by <a class="link" href="gio-GSettingsSchema-GSettingsSchemaSource.html#g-settings-schema-source-get-default" title="g_settings_schema_source_get_default ()"><code class="function">g_settings_schema_source_get_default()</code></a>.</p>

<p>Queries the range of a key.</p>
<p>This function will return a <a href="../glib-GVariant.html#GVariant"><span class="type">GVariant</span></a> that fully describes the range
of values that are valid for <em class="parameter"><code>key</code></em>
.</p>
<p>The type of <a href="../glib-GVariant.html#GVariant"><span class="type">GVariant</span></a> returned is <code class="literal">(sv)</code>. The string describes
the type of range restriction in effect. The type and meaning of
the value contained in the variant depends on the string.</p>
<p>If the string is <code class="literal">'type'</code> then the variant contains an empty array.
The element type of that empty array is the expected type of value
and all values of that type are valid.</p>
<p>If the string is <code class="literal">'enum'</code> then the variant contains an array
enumerating the possible values. Each item in the array is
a possible valid value and no other values are valid.</p>
<p>If the string is <code class="literal">'flags'</code> then the variant contains an array. Each
item in the array is a value that may appear zero or one times in an
array to be used as the value for this key. For example, if the
variant contained the array <code class="literal">['x', 'y']</code> then the valid values for
the key would be <code class="literal">[]</code>, <code class="literal">['x']</code>, <code class="literal">['y']</code>, <code class="literal">['x', 'y']</code> and
<code class="literal">['y', 'x']</code>.</p>
<p>Finally, if the string is <code class="literal">'range'</code> then the variant contains a pair
of like-typed values -- the minimum and maximum permissible values
for this key.</p>
<p>This information should not be used by normal programs.  It is
considered to be a hint for introspection purposes.  Normal programs
should already know what is permitted by their own schema.  The
format may change in any way in the future -- but particularly, new
forms may be added to the possibilities described above.</p>
<p>You should free the returned value with <a href="../glib-GVariant.html#g-variant-unref"><code class="function">g_variant_unref()</code></a> when it is
no longer needed.</p>
